Hi Harvey If you sent it to me this is what I would probably do.A gentle rub over any bare wood with some 120 grit sandpaper, a touch of primer/ undercoat on any bare wood, a cover of gloss or enamel paint to try to match surrounding paint.I can tell you that the skin colour on your Punch is in Humbrol paint. A mix of white, yellow and red ( numbers 22, 69 and 19) in proportions of approx 10:3:1.Follow that with a little stippling on nose cheeks or chin in Humbrol red number 19 and some varnishing over everything to protect and bring it all in together.

However, if you actually send it to me at the end of the season when you can do without him for a couple of weeks, I'll return him a couple of weeks later looking like he did when you bought him. Message me.
